HR Swivel Cradle Wagon Resin Parts in 7mm scale.


 

These accurate 7mm scale resin castings are designed to take the strain out of building a HR swivel cradle wagon, they are not a complete kit, they are aids to scratch building, they are the difficult parts of the wagon. Everything else needed to complete the multi media model can purchased from the trade or can be simply hand made. Below I'll show you how I completed the wagon, my build is not compensated, there are no rocking w-irons or sprung axleboxes, however these could be contrived, it's up to you how you complete the model.

Price for one set of resin parts...£22.50 plus p/pkg at cost £1.50

Order a pair and it's post free.

Order 3 or more and discount is 10%.

The wagon bed is made from Slaters 7mm planking glued to a thickening sheet of 1mm Plastikard. The deck fittings are made from the drawings of this wagon on page 161 in Peter Tatlow's book, Highland Carriages and Wagons, the drawing is essential in order to complete the wagon. Buffers are HR single web type available from Invertrain. The underframe cross members are made from Plastruct 90779 styrene strip, the central section has a sheet of lead inserted for weight. The brake lever suspension point is only needed on one side so the extra one is removed.




The cradle is in place on the wagon bed, the brass corner eye bolts were purchased from Prime-Miniatures. I made a stanchion by turning a length of rod to shape using a file and an electric drill, the little eyes for the retaining chains were added later. I suppose I could have made all four this way but as I had some silicone rubber to hand I made a mould and cast the rest. Tensioning rods, made from 0.6mm nickle silver wire, can be seen in place alongside the cradle side members. The cradle swivels on a central 12BA brass nut and bolt.








I made two wagons as examples as I think they probably worked in pairs in service. The combined w-iron, spring and axle box castings are from my own master patterns, cast in silicone moulds in my workshop. It's a simple expedient and both wagons run very well indeed without compensation. Couplings are hand made, the hook being cut from 1.25mm nickle silver sheet and the links formed on a jig from 0.8mm wire. Suitable couplings, which match the square holes in the buffer beam, can be obtained from CPL. Horse hooks are brass castings which I source form 62C Models along with the brake lever guides, which can be seen to better effect below. I have added a few holes and the pin, which goes into these, dangles on a fine chain attached half way up the guide.



The simple one piece castings were drilled for Slaters' axle bearings then glued to the solebars with the axles in place, providing the axles are parallel in all planes the wagon will run smoothly. Castings similar to these can be obtained from Invertrain.



The brake arm and shoe was cut from 0.7mm n/s sheet and the brake lever from 0.45mm n/s. Retaining chains have been added to the stanchions and the chains, turnbuckles and hooks that secured the load can be seen attached to the corner eye bolts, these can be obtained from CPL Products.
